riorly. The apical two joints of the antennae and the knees, 

 tibiae and tarsi of the intermediate and posterior feet are also 

 pale and the elytra are testaceous brown. The apical bifurca- 

 tions of the head are directed outward and forward, not forward 

 only as shown in Handlirsch's figure. This variation from the 

 type in color is no more than we find in several other species in 

 this genus. The discovery of this species in Rhode Island 

 extends its range far to the north. 



98 Macrocephalus cimicoides Swederus. 



Tampa ; one example. This species is very close to notatus 

 from Central America but the second and third joints of the 

 antennae are shorter and broader and I follow Handlirsch in 

 considering them distinct. 



99. Macrocephalus prehensilis Fabricius. 



Sanford and St. Petersburg. This is a much smaller spe- 

 cies than the preceding with the scutellar keel but slightly 

 thickened at base. It seems to be widely distributed through 

 the warmer portions of the United States. 



Family Aradidse. 



ico. Aradus gracilicornis Stal. 



I took a single example of this species at Crescent City and 

 Mrs. Slosson has several taken in Florida. It is very near lug- 

 ubris but is a more slender insect and has a very different male 

 genital segment. 



10 1. Aradus Falleni Stal. 



Described from Brazil and heretofore reported from so far 

 north as Washington, D. C. I took it at Crescent City, San- 

 ford, St. Petersburg and Clearwater. With the exception of 

 cinnamomeus this is the smallest Aradus known to me. It may 

 be distinguished from the other members of the lugubris group 

 by its thicker and shorter antennae the second joint of which is 

 distinctly shorter than the apical two together. 



102. Mezira granulata Say. 



Taken in numbers from under the loose bark, or more 

 correctly leaf scales, of a rotten palmetto palm on the prairies
